“I am against the line and all its consequences: contours, forms, composition. All paintings of whatever sort, figurative or abstract, seem to me like prison windows in which the lines, precisely are the bars”

– Yves Klein

“There are certainly many ambiguities within the term ‘monochrome’, for all its apparent simplicity and singularity. Incidentally, there are a great many more black or white or grey monochromes in art than chromatic ones. That’s ironic given Yves Klein’s wonderful assertion that the monochrome represents the final liberation of colour from the tyranny of line.”
